Are you trying to replicate from one Gerrit primary to another Gerrit primary (different "instances" - uncommon) or from a primary to a replica (same "instance" - commonly used to distribute read-only load)?

Hi Nasser,

            I am trying to do Gerrit primary (say 10.0.0.2:8082) to another Gerrit instance(10.0.0.3:8082)

Hi Nasser,

Please try not to top-post and instead reply inline. It's easier to follow the conversation that way.

That's not typically expected to work. The different Gerrit instances have separate tracking of code review changes (the change numbers will conflict) and their metadata and there's no published process for how to reconcile those.

Why are you trying to do that?

Hi Nasser,

            My use case is that I have a Gerrit server instance running in one Linux machine whatever repos are created it should be replicated to another gerrit server which acts as just a back up for first Linux instance. 

          Second Gerrit server can be accessed by users when the first Gerrit server goes down

To best be able to help you, we would need more details about your
setup, the config and URLs would be very helpful.

It sounds like you are trying to replicate to the Gerrit ssh port 29418?
That is not recommended,


-Martin

Having a second server available as a "hot standby" is a supported scenario, but you need to configure replication and Gerrit correctly for it to work. Some of that required configuration is documented in the high-availability plugin, but other parts (like replication) might only be in recorded talks or presentations from past user summits. Specific to your issue, it looks like you're trying to replicate to the standby Gerrit instance service, but instead you should be replicating to something lower-level like a filesystem, a git-daemon service, or a git-http-backend service.

      I am trying using replication plugin.All projects and branches are replicated but i m getting error for only refs/changes/xx/xxx/meta . Is it possible to replicate refs/changes/xx/xxx/meta of project via replication plugin .please see below the error message 

[Nasser Grainawi]

I think you need to re-read my earlier reply. It's definitely possible to replicate refs/changes/.../meta via the replication plugin.
